Patent number: 9845930Abstract: A fiber-optic conversion module is provided as part of a lighting device on a vehicle. The module includes optical fibers with connectors, a light exit head, and a converter mounted on a cooling element. Shorter wavelength excitation light is fed to the optical fibers that emit the excitation light towards the converter arranged at an angle relative to the beam direction, at a light spot that remits useful light in a radiation angle in form of a cone of useful light and reflects excitation light as a Fresnel reflection substantially outside the cone of useful light, where Fresnel reflection is made harmless by a light stop.Type: GrantFiled: December 7, 2016Date of Patent: December 19, 2017Assignee: SCHOTT AGInventors: Bernd Wölfing, Volker Hagemann, Jürgen Meinl, Hubertus Russert, Thomas Reichert

Publication number: 20130301999Abstract: Fiber optic devices, methods for producing same, and uses of such optical devices are provided. The method includes combining light conducting rods to form bundles in accordance with predefined rules with respect to a cross-sectional area and number thereof in relation to a surrounding sheath, and are subjected to a drawing process. The strong fiber rod produced by the drawing process has an approximately hexagonal outer shape, and due to the drawing process the light conducting rods also have an approximately hexagonal outer contour. Thereby, a high packing density of about 99% is achieved in the fiber rod. Through a further process sequence of bundling and drawing these fiber rods, high-resolution multi-fiber rods are produced that include several thousand light conducting rods, the diameter of an individual light conducting rod included therein being less than 100 ?m.Type: ApplicationFiled: November 18, 2011Publication date: November 14, 2013Applicant: SCHOTT AGInventor: Hubertus Russert
